If the Receiver is not finishing initialization (the "chase" lights keep going and the right-hand light never comes on solid), then make sure:

You have the Receiver connected to the same router that your Gateway Hub is connected to, that the lights on the power supply, receiver , and the router are all on, and

That your Gateway Hub is checking in to AyrMesh.com

If you are having trouble installing the Receiver in the field, FIRST, be absolutely sure you successfully initialized in (the green light on the right came on, by itself, and stayed on) and that the Receiver is getting power (lights on).

Second, make sure the Receiver is high enough to "see" well over any obstructions and the "label" side of the Receiver is facing the Hub. If the Receiver is facing the Hub and no lights come on (or only the Red light comes on), consider mounting the Receiver higher in the air and/or someplace with fewer obstructions. The light patterns on the Receiver are as follows:

Just the left-most light on - power on, but Receiver not working. Wait a few minutes. Right-hand light blinks while booting.

Left-most light on and adjacent light on or blinking - Receiver working and device attached to the Ethernet port.

Left-most light on and adjacent light on or blinking, signal lights shifting back and forth - Receiver working, connected to router, and trying to check in to AyrMesh.com

Left-most light on, adjacent light on or blinking, and right-most light on - Receiver has finished initialization with AyrMesh.com and is ready for installation

Signal lights:

Red only - signal less than -75 dBm - may not be able to maintain a steady connection
